Understand what software damage to the hard disk is

Hard disk is the most important storage medium in the computer. Regarding the maintenance of the hard disk, I believe that every computer user knows. However, many of the previous articles are aimed at single-player users in the dial-up era. Today, as broadband becomes more popular and large hard drives continue to cut prices, many people will let the hard disk run at full capacity as soon as they turn on the computer: watch high-definition DVDRip movies, and continue uninterrupted BT download, use Windows system restore function... However, you may not know, the new application mode brought by these new software will bring new damage to the hard disk!

The hidden dangers of the new application mode

1. The wrong DVDRip

The DVDRip format video that is now compressed by DVD transcription is quite popular. The resolution of this format is almost the same as that of DVD, but downloading a movie is only 700MB~1.3GB, so many users like to download the DVDRip format to the hard disk and slowly enjoy it. However, playing this format of the film has higher requirements on the system: in addition to the CPU and graphics card requirements are strong enough to ensure smooth playback, the hard disk load is also very large - because playing DVDRip is a continuous decoding decompression, and then sent to the display The process of the system. I found that when encountering a DVDRip file with a coding error, Windows has a very high disk occupancy rate: the system constantly wants to convert the code into a video signal, but the encoded file index and the corresponding signal segment do not match. At this time, the hard disk light will flash continuously, the whole system responds very slowly to the user's operation, and the user clicks on the menu but almost no response. If there are more coding errors, the system sometimes crashes. Many users are very impatient at this time, directly press the RESET button on the chassis or even directly turn off the computer power, this operation is quite dangerous in the case that the hard disk head is not properly reset!

Tip: Windows XP users need to pay special attention. When we automatically preview some large ASF, WMV and other files in Windows XP, although there is no official playback, the computer speed will suddenly change. Slow, hard drive lights flashing and other phenomena, the main culprit is still the video file error code!

2. Bittorrent Download

Bittorrent download is an emerging P2P exchange file mode in the broadband era. Users share resources, and each other is a seed and relay station, commonly known as BT download. Since each user's downloads and uploads are almost simultaneous, the download is very fast. However, it will write the downloaded data directly into the hard disk (unlike the download tool such as FlashGet can adjust the cache, to the hard disk after the specified amount of data), so the hard disk usage is much larger than the FTP download!

In addition, BT downloads must apply for hard disk space in advance. When downloading large files, there will usually be 2~3 minutes. The entire system priority is occupied by the task of the application space. Other tasks are very slow. . In order to make full use of the bandwidth, some people will also perform several BT download tasks at the same time. At this time, it is very easy to cause a crash due to excessive disk usage.

Therefore, unless your computer hardware configuration is quite high (especially memory, at least 256MB or more), before the BT download is improved, if you want to download long-term, multi-tasking applications, it is best Still using traditional FTP software 3. The danger of PQMAGIC conversion

PQMAGIC is a famous partition magician who can freely adjust the partition size and format without destroying the data. However, when PQMAGIC was just launched, the average user's hard disk is about 2GB, and now 60~80GB hard disk is everywhere. PQMAGIC has long been unable to do it: adjusting the partition with data above 5GB usually takes 1 hour. the above!

In addition to the influence of capacity factors, when PQMAGIC adjusts the hard disk partition, a lot of time is spent on verifying the data and detecting the hard disk. It can be seen that in this case, "lossless partitioning" is difficult to guarantee. : Because the conversion speed is very slow and takes too long, during the conversion adjustment process, it is easy to lose data due to factors such as computer power failure and crash. This loss is usually caused by one or several partitions being lost, or the capacity becomes abnormal. In severe cases, the data of the entire hard disk may not be read.

4. The abnormality caused by the hard disk protection software

It is easy to cause the abnormality of the hard disk, and the hard disk protection software. For example, "Restore Wizard", because many people do not pay attention to reinstalling the system or re-partitioning it to uninstall it normally, often the system can not be completely installed. At this point, I want to install and uninstall the "Restore Wizard", but I am prompted that the software has been installed, can not continue, and is in an infinite loop. This type of failure is due to the fact that the "Restore Wizard" took over the INT13 interrupt and controlled the boot of the hard disk before the operating system, which could not be solved with the FDISK/MBR command. Originally this is just a software failure, but many people are inexperienced. If something goes wrong, it will find various partitioning tools to "test" and even rashly and low-level formatting. Under such a toss, the hard disk is likely to die in advance!

5. Frequently defragmenting disk

Disk defragmentation and system restore are the normal functions provided by Windows, but if you do these operations frequently, it is harmful to the hard disk. The defragmentation needs to perform the underlying analysis on the hard disk to determine which data can be moved and which data cannot be moved, and then sort and sort the files. Before the hard disk data structure is formally arranged, it will continuously read the write data to other clusters, and then move the data back to the appropriate position after sorting the order. These operations will consume a large amount of CPU and disk resources. In fact, for the current large hard disk, the proportion of space occupied by documents and mail is very small. Most people buy large hard disks for movie and music. These partitions do not need to be sorted frequently because of the effect of playing multimedia files and disks. The structure doesn't matter at all, the playback speed is determined by the graphics card and the CPU.

6. Auto-restart of Windows XP

The auto-restart function of Windows XP can automatically close the unresponsive process and automatically exit the illegal operation, thus reducing the user's operation steps. However, this feature also has a big problem: it will turn off the hard drive before automatically rebooting, and then turn on the hard drive when you restart the machine! As a result, the hard disk is subjected to two current surges in less than 10 seconds, and a sudden "death" failure is likely to occur. In order to save some energy settings so that the system automatically shuts down the hard disk, it is more harmful than the hard disk.
Remedy to eliminate hidden dangers

1. Resolve coding errors

The best way to encounter a coding error video file is to issue a shutdown or restart command to the system through normal channels. Wait patiently for the system to restart itself after processing it. Then go online and search for some software that fixes coding errors to fix these videos and watch them.

2. Increase system cache

For BT like this thread is not optimized, while reading and writing to the hard disk software, if you must use, you can modify the registry Increase disk buffering to reduce the frequency of hard disk read and write. Take Windows XP as an example:

Click "Start", "Run", type "Regedit" and press Enter to open the Registry Editor. Expand the HKEY_LOCAL_MACHINE\\SYSTEM\\CURRENTCONTROLSET\\CONTROL\\SESSION MANAGER\\MEMORY MANAGEMENT branch, right-click in the right window, select New, DWORD value, name the new value Iopagelocklimit, and set its value Set to "4000" (hexadecimal, ie 16MB) or "8000" (ie 32MB), so the hard disk read and write frequency will be reduced a lot. For the problem of excessive CPU usage caused by BT, you can solve the problem by adjusting the priority of the task: press "Ctrl+Alt+Delete" at the same time under Windows 2000/XP, select "Task Manager", and then click On the Processes tab, right-click on "Btdownloadgui.exe" and select a level below "Standard" under "Set Priority". However, this adjustment sometimes causes the BT to illegally exit.

3. Cleverly uninstall "Restore Wizard"

If you have the "Restore Wizard" installed on your computer, but forgot to uninstall the "Restore Wizard" correctly before reinstalling the system, it will not be able to partition and Install the system, then try to solve the problem by using the following methods: After starting the computer, press the "Ctrl+Home" key combination before the system boots, call up the "Restore Wizard" menu, enter the password and select "Uninstall". You can also put the "Restore Wizard" installation CD in the CD-ROM drive, find the uninstaller Uninst.exe and execute it. When the prompt "Can't run on... Do you want to restart the computer?" appears, click "OK" to restart Install the Restore Wizard after booting and then uninstall it. This method is verified on the "Restore Wizard" version 5.0, 2002, 2003 and other versions.
4. Accelerate the operation of PQMAGIC

Open "PartitionMagic Preferences" under "General" option in PQMAGIC, "Ignore OS/2 EA error on FAT" and "Skip bad sectors" Check that both options are selected, ignoring the process of verifying the data and detecting the hard disk will naturally speed up the PQMAGIC. Of course, before using PQMAGIC to operate the partition, we should first use the disk scan tool to check and repair the error on the hard disk, and then perform the partition conversion operation.

In addition, it is best not to use PQMAGIC to adjust the partition with data, not to change the partition format when partitioning format. The best way to do this is to back up the data on the partition you want to adjust to a partition that doesn't participate in the tuning (preferably on another hard drive), and then empty one or more of the adjusted partitions so that the conversion is much faster and safer.

5. Partitions using NTFS format

The benefits of NTFS partitions need not be said here? Because the NTFS partition itself has a small cluster and is not prone to disk fragmentation, Microsoft has also made special treatments on file allocation tables and directory indexes. It is easier to recover files in case of errors. However, in order to ensure system compatibility, it is best not to set the boot partition to NTFS format.

6. Disable automatic restart function

Right-click "My Computer" in Windows XP, select "Properties", then click the "Advanced" tab, click " Startup and Recovery button, in the open interface, clear the check box before "Automatic restart" under "System failure". However, Windows XP will automatically restart when the system encounters a serious failure such as graphics driver compatibility. But at this time, Windows XP will generally become a log file, so that you can check it after booting. At this time, you must press the RESET button to start the time to prevent Windows XP from shutting down the hard disk.

7. Turn off the hard disk energy saving function

First set the hard disk energy saving to "DISABLED" in the power option in the BIOS, then in the "Control Panel" and "Power Options" of Windows. Set "Shutdown Hard Disk" and "System Standby" under "Power Scheme" to "Never" (for system shutdown and hibernation, or manual control).
